Switch

abey · #1 (**permalink**) 09-26-2005

using switch can we match for more than one values..

eg:

switcha(a)
{
case 1, 2, 3: printf("ddd");
break;
case 4, 5, 6: printf("mmm");
break;
}

In this case wat i found was only for the last value, i.e 3 and 6 the switch works.

I'd greateful if someone can help me in solving this out(using switch or any other alternative).

Code:

{
case 1:
case 2:
case 3: printf("ddd"); break ;
case 4:
case 5:
case 6: printf("mmm"); break ;
}

This should work.

thnx, tht works....

is there anyother option to implement this apart from switch, that wil reduce the number of lines.

You can go ahead with the if-else-if combo.

Actually that's what you use switch for, it is much easier to read/debug switch statements than the if-else-if-else... combo. It also makes it easier to extend the program if you want to check for more conditions - you just have to add case statements as required instead of entire if-else blocks.

If you have more than two conditions to check for, you are best off using switch.

use if......
if((a==1)||(a==2)||(a==3))
